Abstract

Yukon residents often must travel long distances to access specialized cancer care, which may impact cancer treatment patterns. We conducted a retrospective study to characterize all adult breast, prostate, colorectal, and lung cancer cases from the Yukon, diagnosed from 2009 to 2021 and seen in consultation at BC Cancer. We collected data on demographics, tumour characteristics and treatment, including timepoints for cancer care. A secondary analysis of non-referred cases was conducted. There were a total of 336 breast, 270 prostate, 279 colorectal and 266 lung cancer cases diagnosed in the Yukon from 2009 to 2021, of which 298 (88.7%), 120 (44.4%), 206 (73.8%) and 204 (76.7%) cases were referred to BC Cancer, and 266 (79.2%), 118 (43.7%), 204 (73.1%) and 183 (68.8%) were included in this study, respectively. Most cases were diagnosed at an early stage (breast: 92.9%, prostate: 82.2%, colorectal: 72.1%, lung: 45.9%). Nearly 70% of cases resided in Whitehorse (Yukon’s capital), where most Yukon residents live. Compared to available published Canadian timepoints, Yukon patients had similar or shorter wait times in 13 of 22 timepoints along the pathway to diagnosis and treatment. However, time from biopsy to surgery had the longest relative wait times across all tumour groups (range: 26–60% longer). Our study provides baseline data that can help inform cancer care provision for Yukon residents.
